Marché Soupson, the "soup depanneur" at 149 Jean-Talon W. (corner Waverly) uses coconut sugar in their addictive spiced spanish marcona almonds roasted in-house and brownies. The owner is really nice - I'm pretty sure if she doesn't stock it on the shelves, she would sell you some from her supplies and suggest other places to get it. I highly recommend their soups, which change daily and are all vegan.
